Maybe untreated strep throat. Cbc blood!

So about 4 months ago i was diagnosed with strep throat although the the infection was all in my uvula i didn't have any white patches on my tonsils and my tonsils weren't swollen, my doctor prescribed me penicillin which worked really fast clearing up the infection in my throat but unfortunately i didn't finish the antibiotics due to direhhea and my lack of knowledge of how serious strep is and there was still a little bit of the infection left in my uvula which still went away on its own but now i have been dealing with what looks like a chronic pharyngitis or granular pharyngitis for about 2 months now and i don't know what caused it, I'm scared that maybe i didn't treat all of the strep and there's still bacteria left in my body and i've been reading stories on how people had strep throat and it traveled down into their abdominal and they ended losing limbs to this. Can you inform me how you think my granular lesions happened and would the strep bacteria be detected in a cbc blood
